This quote is completely and totally irrelevant. Nobody is saying they should code a new Outlook. If they did code something, it would be significantly smaller in scope and rigorously tested like spacebound programs in the past were. "New space-engineering-grade code created with actual engineering practices" is absolutely going to be more reliable than "old bloated commercial shitware". But I guess software engineering is a lost art, so it can't be helped.

It's also going to take a hell of a lot longer and cost more than buying an Outlook license. If I was lead on that project, you'd have an uphill battle trying to convince me that spending $100k+ on an email solution unless you can point to specific, serious deficiencies in the existing off the shelf solutions.

Software Engineering is far from a lost art: part of the practice is intelligently making cost-benefit decisions.

The current solution is literally causing problems in space. Space-grade engineering is expensive, but having things go wrong on your already very expensive mission is even more expensive.

Until we've had this failure, I do agree that using COTS software was the logical choice. And now we know better.

Sure, but people who didn't know better until this particular incident do not deserve the title "engineer". Being able to classify and manage risks before they happen is engineering 101.

Engineering requires working around constraints as well - and a major constraint of any project I've worked on was budget. If they wrote a new email client and it had some bug, we'd be laughing about why they didn't use one of the COTS email clients.

It’s a personal communication device. It’s not mission critical.

Alpine and Mutt are about 20 and 30 years old, respectively.

Alpine and mutt are about as far from bespoke as it gets. Both are far less likely to suffer from bugs than outlook.
